伊朗采购需求：玻璃纤维、短切玻璃纤维、3D玻璃布、玻璃纤维粗纱、活性碳纤维、短切毡

I'm looking for high-quality hollow glass microspheres specifically designed for biomedical applications. The dimensions I require are between 16 and 20 micrometers. It's essential that these microspheres possess excellent properties such as biocompatibility, low density, and uniformity in size to ensure optimal performance in various medical devices or drug delivery systems. Could you please provide detailed information on the available products that meet these specifications? Additionally, I would appreciate any insights regarding pricing, minimum order quantities, lead times, and potential customization options. If you have any sample materials, that would also be greatly beneficial for my evaluation process. Looking forward to your prompt response!
